IsoPlexis' original scientific leaders from Yale, Caltech, UCLA and Memorial Sloan Kettering Cancer Center initiated research and developed core technologies to detect cellular responses at the single-cell resolution, in order to better understand how to develop potent personalized immune therapies for various cancers. IsoPlexis has expanded that original technology to create a next-generation system, capable of identifying and predicting patient responses to immunotherapy more accurately than conventional assays. More recently in 2017, researchers from Kite Pharma, NIH and Yale presented data from IsoPlexis collaborations in CAR-T, anti-PD1 and other immune therapy areas to advance biomarker discovery for immunotherapy. IsoPlexis enables researchers to accelerate the fight against cancer by providing a simple approach to understanding the complex role of immune cells that determine patient outcomes. The IsoCode assay and IsoLight, IsoPlexis' single-cell precision platform, can capture previously unseen 42 different secreted proteins per cell, across thousands of single cells simultaneously. The result is a precise functional profile of tumor-reactive T-cells in each patient, which enables researchers to better predict and understand complex cancer patient response. The system is also being used to advance research and therapeutic development in infectious diseases, as well as multiple sclerosis, systemic lupus and other high-need areas. "This latest funding round allows us to continue our work to advance the fight against cancer," said Sean Mackay, IsoPlexis Chief Executive Officer and Co-Founder. "Using the IsoPlexis technology, our partners are beginning to gather data to help improve future treatments for the patients with the highest need. This new funding will help us build on our momentum, and is a reflection of our investors' optimism around the IsoPlexis system." "IsoPlexis' collaboration data and product development has continued to demonstrate both the need for the IsoPlexis technology and the potential to have a large impact on improving patient outcomes," said Gregory P. Ho, President of Spring Mountain Capital and IsoPlexis Board Director. "We are excited to continue our partnership with the IsoPlexis team to move the company forward." IsoPlexis will use its new funding for continued product development and marketing, enabling further use of the IsoCode assay and IsoLight system by leading trial centers and biopharmaceutical companies focused on oncology and a growing list of other important disease areas. "IsoCode, the core technology of IsoPlexis, can uncover the complex and somewhat mysterious role of each T cell in the battle against tumor cells. More importantly, it is a robust technology, readily adaptable in clinical settings, to generate individualized patient immunogram profiles such that we have a much better understanding which patients will respond to which treatments. I am excited by the current progress, and look forward to greater and broader impact in immunotherapy and other important therapeutic areas," said Rong Fan, Ph.D., IsoPlexis Co-founder and Scientific Advisory Board Chair, and an Associate Professor of Biomedical Engineering at Yale University. IsoPlexis, a privately held life sciences company, is developing novel technologies at the forefront of the revolution in immunity-based treatments of cancer. Using a next-generation diagnostic and therapeutic platform to identify patient responses at the single cell level, IsoPlexis' original scientific leaders from Yale, Caltech, UCLA, and Memorial Sloan Kettering Cancer Center have advanced understandings of personalized therapies against various cancers. IsoPlexis is venture funded by Spring Mountain Capital, North Sound Ventures and Connecticut Innovations, as well as supported through grant funding from the National Cancer Institute and the National Institutes of Health.

IsoPlexis Corporation (IsoPlexis), a venture-capital funded life sciences company developing an innovative cellular response analysis platform to measure the proteomic function of individual cells in patients, today announced it was recently awarded a competitive Phase I Small Business Innovation Research (SBIR) grant from the National Cancer Institute of the National Institutes of Health to develop a multi-protein, single-cell analysis platform to facilitate personalized cancer immunotherapy response detection. The funds for this SBIR grant will be used by IsoPlexis to advance the commercialization of a cell capture and single-cell protein analysis technology, addressing a rapidly growing need in cancer immunotherapy. This technology will not only provide comprehensive single-cell information to address biological and biomedical questions in academic research, but also offers a solution for the biotech and pharmaceutical industry to monitor patient T-cell function in antibody-mediated T-cell immunotherapies. "We continue to see a need to understand differences in patient responses to immunotherapy, and we are excited to be in a position to address these challenges with our platform," says Sean Mackay, CEO of IsoPlexis. "This award will help IsoPlexis commercialize our single-cell response profiling technologies in immunotherapy, and provide an important new solution for developing better biomarkers to address a critical need." IsoPlexis works with pharmaceutical companies and academic labs to test the efficacy and safety of new therapies in various areas of immunology, oncology, and other emerging disease areas. "We look forward to developing a better understanding of the cellular cytokine and chemokine responses pre- and post-immunotherapy, specifically those from T-cells, to better understand their role in response to the therapy and disease progression," said Tim McConnell, Director of Innovations and Operations at IsoPlexis, and the primary investigator of the project. IsoPlexis’ single-cell barcode platform (SCBC) improves upon existing solutions by providing highly-multiplexed, functional, secreted protein readouts, at single-cell resolution, to advance detection of important drivers of immune system activity. About IsoPlexis: IsoPlexis is a life sciences company developing a cellular response analysis platform that identifies a wide range of patient immune responses at the single-cell level. Its platform can assess safety and efficacy of therapeutics and monitor disease progression, enabling improved therapeutic development, and informing physician decisions.
